"To c1510? 1' it may-cancer ll it Known that I, JOSEPH B. CHERNEY,

..aul ee, in the county of ll'lilwaukee lids of cabinets, chests, trunks and other receptacles, as well asto insureof retension of such lids in lifted position against auton; no closing, said invention being espelids of gramophone and 'gramophone cabinets, said lids being then supported in lifted podtion until manually closed.

Ware 1 of the drawings,represents a sec-. view of a fragment of a graphophone or amophone cabinet provided with automatic lid-lifting and supporting means in accordance with my nvention, the plane of the section being indicated. by line 11 in th next described illustration; Fig. 2, a deta 1 plan View partly in horizontal section indicated by a line in Fig. 1, and Fig. 3, a detail elevation partly in section as indicated by line 3- 3 in Fig. 2. 7

Referring by numerals to the drawings, indicates the body of a 'grapho'phone or gramophone cabinet, and 5' thelid of'the cabinet in hinge connection with said body. The lid is fastened down in its normal posion by any suitable means, the means shown being a spring-latch 6 and a keeper 7 applied to the cabinet-body and said lid respectively. To provide for manual disengage.- ment of the latch from its keeper, said latch is attached to a push-pin 8 that extends outside of the cabinet-body.

"Rigidly secured in the cabinet-body. to

project at ahght-angle to a side wall of the same, is a supporting block 9, and bolted or otherwise suitably fastened to the block is a bracket 10 inwhich a lateral spindlecnd 11 of a lever 11 is journalcd. Connected at its ends to the bracket and le'ver respectively is a spiral-spring 12 of suitable power surrounding the spindle-end 11 of said lever. An annular inner flange 11 of the lever, concentric with the spii'idle-end n the. United States, and resident i ate of Wisconsin, have invented cer-" hon newand useful.- lingroycments 1n Lid-;

cially designed for automatic lift of releasedof said lever', is radially toothedto nroyide for the tensioning of the spring 12, the ad said. spring being caught 'oe- 1 jacent end of tween some two of the flange-teeth.

Piyotally supported atr its lower end in a v fork of the lever 11 is a link-bar, 13, and the upper end of this bar 1S pivotally secured to a platel-zl fastened by screws or other suitable means in the lid of the cabinet. I The link-bar is guided ina slotted plate 15 fastencd by screwsor otherwise on the bottom 16 of the upper compartment of the cabinetbody over a slot in said bottom.

' A link 17 is employed to connect the lever 11 and an extremity ofa lever 18 of the first class herein shown fulcrumed on a block 19 that is fastened, by conveniently disposed screws 20, to the aforesaid sidewall of the I cabinet from which the block 9 projects,

.bothbloclrs being suitably joined in abutting contact to form a supporting bracket for other parts of the herein described me'chanism. Shown iii connection with the blocks, at their intersection, is a'permanent stop 21 to limit upward movement on. the part of the lever 11, but said step may be sometimes omitted. The'ot-hei' extremity ofthe lever 18 is connected by a link 22 to a piston 23 in an air cylinder 24, shown as having its rent regulated as to area by the adjustment of a slabbed screw 25, and the cylinder is provided with apertured cars 26 through which fastening screws 27 extend into the block 19.

It is within the scope of my y i a5. herein claimed, to omit the block 19 and secure the lever 18 and air cylinder 21- direct' to the adjacent wallof the cabinet or other receptacle.

In rac ice there is contraction of the spring 125, when the lid of the receptacle is lowered, and at the same time the piston 23 is moved in one direction of its play in the resistance to prevent slamming of said lid. The

air cylinder against partial vacuum lid being fastened down, the various morable parts of the herein described mechanism remain in the positions shown by full lines in 1, but said lid being released, the spring positions shown by dotted lines in said Fig. 1. there being a gradual automatic lift of the aforesaid lid against compressednir resistance occurring in the cylinder 2i back of th piston 23.

12 reacts to shift said parts to the The part 27 appearing in l ig. 1, is the n motor-wind crankshaft of a graphophone i p o e' and 'c6nst1t 1tes'"no Parto y invention. v

p at a right-angle to a sidewall ofthe same,i a: bracket fast on the block, a lever having a" 1 claim: p v '1.- Thecombination-of a receptacle. having a hinged. lid, a block rigid in the receptacle lateral spindle-end *journaled in the bracket,

; as'piral-spring surrounding said end ofthe lever and tensioned .in connection with said. lever a d bracket, a link-bar. in p1votal'con-- 'nection with the-lidand lever, means in connection withns'aid lever .for checking, movement of the same inopposite directions, and neansfior fastening said lid in closed poition.

The combinationiof a ieceptacle having.

ahinged'lid, [a block rigid in the receptacle at a right-angle to "a side wall of the same, abracketfast on the block, a lever having a lateral spindle+end journaled in the bracket, a spiral'-- spring surrounding; said end of the lever and tensioned in connection withsaid lever and bracket, a'l-ink-bar in pivotal connection withthe lid and lever," means in connection with said lever for checking movement of the same in opposite directions, a stop exte'ndingfrom said block in the-lifting-path of the lever, and means for fasteningsaid lid in closed position.

.j 3.- The combination of a graphophone or granioplione cabiiiet hav ing a hinged lid, a

' jfixed plate in the lid, a spring-controlled lever fulerumed in the cabinet below thev bottom of an upper compartment of the same,'a slotted plate in connection with said bottom, a link bar guided in the slotted.

plate and. connected to the leven and the,

other-'ofisaidplates, means for fastening the 1 lid in closed position, and means in (ionnec tion with said lever for checking movement ofthe same: inopposite directions. 1

4. The combination of a graphophonaor it gramophone cabinet having an upper-com the lid in closed position, and means in 'connection' with the lever for checking ihovement of the same in opposite directions.

In testimony that I claim the foregoing I "have hereunto setmy hand atMilvva-ukee in the county of Milwaukee and State ofWis j n inthe presence of two witnesses. Y a
